and State of l-Fisoonsi-n, have invented new and useful ImprovementsMountings of Ri'mless Eyeglasses, ot i which-tire followingisa-fspeeiiifcation:

Figure 1 represents a rear view of"a pon' tion of one of the lenses withthe bridge mountings connected therewith.

Fig. 2 is a vertical section drawn on line m, at of Fig. 1, looking inthe direction of the arrows.

Fig. 3 is a transverse section drawn on line y, y of Fig. 1, but showingin addition thereto a complete lens with a section of the mechanism forconnecting one of the bows thereto.

Fig. 4 is a perspective view of one side of one of a portion .of thelenses, showing several clamping members for connecting the bridgemember or nose piece thereto, and

Fig. 5 is a vertical section of a portion of one ci the lenses taken online e, e, of Fig. 3.

Like parts are identified by the same reference numerals throughout theseveral views.

1 represents one of the lenses of the eye glasses. 2 is a bridge or nosepiece. The nose piece 2 is formed integrally with the two clampingmembers 3 and 4, which are adapted to nicely fit one end of the lens 1.

'l he members 3 and 4 are connected together by Shanks or central member5 and the central member 5 is provided with a threaded aperture 6 forthe reception of the screw 7. 8 is a wedge member which is provided witha smooth aperture 9 for the reception of said screw it. The wedge membere is.' pro vided at; its respective ends witlr transversely Aarranged'pms 10 which arefformed integrally therewith, and the llens 111 isprovided l with aperturesll, 11 for tires-reception `*of* said pms 10Jl/Vhen assembling my deaf'icefthe angular projections 510 f are `firstinserted in the apertures 11 ofthe-denses,-the Llenses are Athien placedb'etween ithe clamping members 3 and 4`respectively, Ywhen'saidwedgememblersare retained inaplacebyfthe screws 7,

said screws being turned down I'iirmlyi inthe "threadedapertures 6against' thecollar` 12 surrounding the aperture `9,whereby =th`ewedgemember 81 iseseeurely retained in place and 3prevented 1fromwabbling -oribeing with draw-n from between 1 the olampingmembers.

VV-henthertwo opposing lensesare connected with the b'ridge2 by the;mechanisindescribed, the: clampingA members 13 land? 14 are-'in likemannersecured to ytheopposite end Vofthe lens` l, as shown in Fig. Theclamping 'members 13"and14l are 'frmedim tegral with the shank 15. rlheshank 15 eX- tends rearwardly at right angles to the lens, as shown insaid Fig. 3, when the bows 1G are connected therewith by the pivotalscrew or pin 17. When the clamping members 13 and 14 are in place, asecond wedge member 18 is inserted between the Clamping members 14 andthe lenses and said wedges are retained in place by the screws 19, whichscrews have threaded bearings in apertures 2O provided therefor in saidshank members 15. While but one of the lenses are shown it will bevunderstood that two such lenses are used and the outer end of each lensis provided with similar mechanism to that shown on the right hand sideof Fig. 3.

lt will, oi course, be understood that the wedge member 18 is providedwith an aperture 21 for the reception of said screw 19. It will beobvious that by thus connecting Jthe lens 1 with both the bridge 2 andbows 16 through two integrally formed mountings, and that by insertingthe respective wedge .members 8 and 18 between such lens` and theopposing mountings, as shown in Fig. 3, said lens is not liable tobecome loose in the mountings for the reason, among other things, thatsaid wedge members 8 and 18 are each provided with two transverselyarranged pins 10 and 10', and each of said wedge members are retained inplace by screws 7 and 19, respectively, whereby such wedges are securelyretained in place, while owing to the tact that said wedge member'sarel'connected with the lenses l` through said transversely arranged pinslocated at a considerable'distance apart, said lenses are not liable tobecome loose in their mountings. The wedge lmembers 8 and 18 VK 'and theopposing clamping members are preferably provided with shallowrecesses22, 28, 24 and25, whereby such parts are adapted to yield slightly underthe pressure of the respective screvvs and 19, as suchscrevvsvarevturneddown in their bearings,

f whereby the liability of fracturingr the lens j isavoided, and saidparts are caused to more securely impinge the lens yand retain the sainemore securely in their mountings.

Having thus described my invention what I claim as new anddesire tosecure by Letters Patent, is-

l. In a .device of the described class, the combination of a lensprovided with a plurality of apertures, a lens mounting comprising apair of clamping members connected together by ashank, a wedgememberprovided at its respective ends with angular projections adaptedto enter the aperl tures in said lens, and means for retaining saidwedgemember in place between one of said ,clamping members and such lens.

.2. In av deviceof the described class, ay

lCopies of this patent may be obtained for pair vof lenses provided witha plurality of apertures, a pair o' lens mountings each comprising apair 'of clamping members,

said clamping members being adapted to engage the respective oppositesides of said lens, wedge members provided at theirends vwithv angularprojections adapted to enter the apertures in saidlenses, and 4means forretaining said wedge members between the opposing surfacesof said.lenses and clampingmembers.

3. In a deviceof the described class, a pair of lenses each lensprovided with :i

plurality of apertures, a pair of lens mount.

ings, a bridge member formed integral with said mountings, eachcomprising` a set oi vecnts each, by addressing the Commissioner ofPatents, Washington, D. G.
